Answer:
Never
Step-by-step explanation:
If the slope is the same and the y-intercept is the same
They are the same line
2x + 5 = y is the same as 2x +5 = y
7 1/8 is greater because in decimal form, 7 1/8 is 7.125 and that's greater than 7.025
You can find the zeros of a polynomial by first factoring it completely. Then, you use the Zero Product Property (Z.P.P) to make each term equal to zero. Finally, you just solve for the given variable, and you will have the zeros.
For example:
x²+4x+4 = 0
1. Factor The Polynomial:
(x + 2)(x + 2) = 0
2. Use Zero Product Property:
x + 2 = 0
x + 2 = 0
3. Solve for variable:
x = -2, -2
Therefore, the zeros of the polynomial are -2, -2.
Hope I explained it well and have a fantastic day!
Answer:
x = 3
x = -1
Step-by-step explanation:
First you wanna assume that y is 0: 0
- 2x - 3
now factor the right side like any other problem:
we know that we automatically have (x _ ?)(x_?), because there is an x squared
now we need to find a number that multiplies to -3 and adds up to -2
if take positive 1 and -3, we multiply it to get -3, and when you add the two numbers, you get -2
so now we can fill (x _ ?)(x_?), and turn it into (x - 3)(x + 1)
now we will take each parenthesis part and separate it and solve them for x individually:
(x - 3) = 0
x = 3
(x + 1) = 0
x = -1
so now we have our x intercepts
